Do you have a problem with that? I did at first but i was told by many php experts that it does not matter! Do you think that this forum was made by Programing Talk?
The reasons why we chose to base the site on PHP Nuke were:
1. To save time.
2. To see how popular the site would become.
If the site becomes well used we will be willing to invest (today) upto $300 in paying a professional to make the site. In about a year we will look to see how much the site has made and then decide if we pay a professional how much the job will be worth.
