Request a program.

Seriously, request programs. I prefer web based stuff but all suggestions are welcome.
I'll charge USD for sufficiently "advanced" programs that you suggest.
If this is against the rules, please feel free to delete it @ mods+

Anyway, one example would be this web based php "worm" I'm thinking of.
Perfect for advertising because it sends a PM as the user viewing the page.
Hell, I'd even toss in a few checks for a typing style via the user's about me if i were you (assuming he or she doesn't have private profile) and have it select a mode based on phrases like " ur " and "r u" and stuff.
Oh, maybe mix up words via thesaurus or something, but that would cause problems because the user won't stay on a random page long enough for it to send individual messages unless the ad worked on them lol


TL;DR
Post ideas for programs that you would actually use.
Might charge @USD for some that are awesome.
