ok if you want to insert a sig go to user control panel and go to edit profile and to signature. like jim hat said put [/img] before and after what ever your pasting in there.
an attachment is easy. the pic of whatever needs to be saved to your computer under my documents ect. then when you go to make a thread look for a thing that say attach and it will bring up your documents or whatever. click what you want to attach and it will come up when you post.
hope that was a good enfough explanition. shit aint easy to explain tho. -out
