Twitter help

[varigatedivy]

I want to set up another twitter account but why does it limit my twitter user name to a number of characters? Is there any way round this?

it is very common to have a character limit on a username field, twitter are far from the only ones to do this.
You can't get around it, and you should also be aware that if someone tweets you, or uses the old-style retweet, the characters for your username come off the available character limit for the tweet, so you may end up getting edited.
