I am interested in going into t-shirt design, and printing - mainly for business experience.

Recently I have seen a lot of t-shirts that have trademarks printed on them, such as the Starbucks Coffee logo, and also characters that I would think would have some sort of protection (like Disney) have been on a lot of company's t-shirts recently. Does one need special permission to print such things onto a t-shirt?

This is a question I don't seem to be able to find the answer to:

Is there any document/law that states how long a student in further education (college) in the UK can be kept working in class by a lecturer without taking a break/rest?

I heard that Alicia Keys and Rihanna are performing on The X Factor in a couple of weeks but then wondered which one would be the headline act. It's quite tricky because Rihanna has had more number one singles in the UK but all of Alicia Key's singles have reached number one in the US and she has 12 GRAMMY awards compared to Rihanna's 1 GRAMMY. What do you think?

I live in the UK and have an iPhone that is locked to o2 but when I go to Spain, can I put a movistar sim card in to the phone, as movistar is part of the same company as o2, mainly to avoid roaming costs?

I recently upgraded from an iPhone 3G to an iPhone 3GS. I noticed at first push emaill wasn't working, I thought the only thing I could do was restart it, which I did, and it worked for approximately another few hours then stopped again, this is just a process that keeps on and keeps on happening. Is there anything else I can do? This is Yahoo mail push by the way!

Is there a certain way to tell when you have stopped growing, puberty is over, etc...?

For example, is there a certain time where certain growth happens for example:

- Height stops and then chest hair starts to grow?

- Height and chest hair grow in harmony?

- Or is it completely random?

I guess it's completely random but I'm not sure.

You might be bored of these questions now but I am just wondering...

I am almost 17 and am 6ft2. The only other height from my childhood that I can remember is that at the age of 14 I was 5ft9. What I want to know is am I likely to have another growth spurt, obviously I know no one can be accurate so just want opinions... Thanks.

My Mac boots up fine, but stays on the Apple and the wheel grey screen eternally. I have tried reinstalling Leopard and it installs recovery disc one but just goes into the loading screen for ever again once I put in recovery disc two. I'm not sure what it is as I have tried installing Ubuntu too and that gets stuck as well. I don't know what it could be?

I have been producing, recording and marketing music for a few years now and now I want to go further and actually setup my own online music store. Web-based similar to say 7digital. But I don't know where to start. I was thinking a distributor? But don't know where to find one.

I find this quite difficult, it's probably really ease. What is the HCF and LCM of 3 and 45? Is there a method of doing it or is it just trial and improvement?

I have been using Apple's iChat for a while now and recently when I went to login, I noticed that it said 'Get an iChat Account', so I was curious, so followed the link and signed up for an iChat Account. It was totally free and it is an @mac, why was it free? Is it only a trial? Or a limited account?

For example when I look on Google or Yahoo Finance and I find out that for example, Apples share value is $110 or whatever it is. How is that determined? Who determines it? Also with like DOW JONES or FTSE 100, how is the share price of that determined?

I was watching the national movie awards last night and was listening to Samuel L Jackson's Special Recognition Speech about Pixar. What did he mean when he said: "Pixar was founded by George Lucas, whatever happened to him? Then it was bought by Steve Jobs, whatever happened to him? What did he mean by the 'whatever happened to him' part. Because I thought and thought and couldn't understand it?

I remember when the first iPod was released, it was like we invented firewire so you're gonna have to use it. But now it's not an option. Firewire can only be used for charging?

When people buy shares in a company, depending on how many they own, say for example there are 100 shareholders, does that mean each shareholder owns 1% each and when they cash in their shares, they get 1% of the current profits?
