Xrumer question

I have the 15 day trial of "XRumer Autosubmitter" Can someone just tell me how to make it so that I can have my account on another forum spam in a certain section to increase posts? I'm not doing this for marketing just to increase post count on another forum. Also, if there is a program easier and cheaper than Xrumer please let me know ^^

This tool doesn't submit to forums as far as i know.It's for submittting to cataloges and searchengines.

ah, thanks, I've been trying to find a decent spam bot but nothing seems to work out besides macro and it has a lot of down sides. =/
