Don't buy from Alstrasoft! This paid to post forum script is very buggy, full of security holes and very poorly coded. Their support sucks (provided you can even get a response from them in under a week). Do your homework and save yourself some headache and money

I spent nearly $300 on their "askme pro + paid to post" scripts and then had to pay an additional $150 to a 3rd party programmer to fix the security exploits.
