Simply type in the profile text OR cut and paste from the profile from you computer or FaceBook.
The more text you have for the profile the text box will expand till it is all in.
This is where the green guide lines help.
Any just for a bit of interest in the text I normally highlight the animals name by putting it into bold text
Also anything that is very important text (such as ..."All Applications for this animal are now closed " just highlight the relevant text and goto the Text Settings on the right, click on "Colour" and select the colour you want.
If you want to make your email address in the text a hyperlink
such as email@example.com
Just highlight the text as above and after you have added the link the text will be automatically underlined (as above)
