Welcome!!! And dont worry. We got some killer 99-04s to get some ideas from too. :-D
to add pictures simply click the button in the reply box toolbar that has a little tree on it with a black dot at each corner. ... its supposed to look like a picture. Lol.
Anyways. After that click the "post from url" tab in the pop up box. The uncheck "host locally" and paste the picture's url into the adress area given.
Or. A faster way is to simply paste the picture's url into the text area then put [.pic] before it and [/.pic] after it but dont include the periods. Lol.
I hope i didnt just over complicate the hell outta that. Lol
