We are having some difficulties with that...
Seems like the board software does not differentiate between edit and delete and the problem is with the first post. If that gets deleted then so does the topic and that could be problematic because we don't want whole topics deleted.
So my iT guy locked edit at 30 minutes until he figures out how to solve this issue.
The board software is written to be very easy to use so it does not have a lot of customizations unless you code them in and I am currently discussing that options with iT.
I have been thinking about maybe switching to ZenForo but it's not cheap at $160 +$55 yearly + possibly copyright removal around $300. Then a proper skin and mods all of which are paid.
There are advantages to our current software because there are so few scripts available. Our PM system for instance is so basic that no spy script is available. Our forum software cannot spy on members private messages where boards like ZenForo, MyBB and most other top software easily can.
We do not store IP's, and private information. In fact we stripped out almost everything that compromises privacy. As soon as we switch software these privacy invading features come as part of the software package.
On our boards even mods get no IP info or anything more than each member sees. Even the admin only has very basic information like the last used iP address which is hidden from everyone including mods.
So right now I'm trying to balance privacy with features and we have to decide what we want. I can adjust the edit time to anything but the worry is always the first post which if deleted causes us some big issues.
Everything is in Beta right now and before January 1st so we can openly discuss what we want ands we can easily switch software. That comes at a risk in the privacy department because my iT guy assured me this software is the most privacy oriented software there is. So we have to decide features vs privacy.
