1. When you have the page open with your roleplay or character in it,highlight and copy the line in the browser that looks like this
http://www.roleplaycity.com/forum(only your thread will have numbers and things at the end)
2. Go to New Roleplays, advertise the link, highlight the word or words that you want to be a link (like; 'join me now' or 'click this link') OR Go to your signature and highlight the name the sheet belongs to.
3. Above the row of smileys, there's a bunch of buttons. You want to press the button of a blue circle/world with a page. Hover your mouse over it, and it will say 'Insert HyperLink'.
4. Press it and around your highlighted word the code 'URL' and 'URL' (in the brackets) You must put in an = symbol after the first URL and then your pasted link, so it looks like this:
(URL=
http://www.roleplaycity.com/forum) Linked Word(/URL)
take note that you would have square brackets around the URL codes, and no spaces, I can't show this code properly as a help file unless I put in parenthesis instead.
