The default attachment types allowed on phpbb is kind of restrictive, but I have the ability to add a lot of different things, including custom file types (SolidWorks, Solid Edge, etc). Don’t be surprised if you try to attach a ZIP file and you get a Netscape icon (ships wheel). The site groups several extensions into a group, and you assign an icon.
Anyway, there are limits to numbers and sizes and types of attachments for posts and private messages. I’m trying to open things up without causing any problems.
The big problems I’m trying to avoid here are:
eating up too much server space.
eating up too much server cpu bandwidth
allowing potentially harmful script files
So if you run up against something you want to do but can’t do, let me know. Chances are I can help you.
Yeah, phpbb is set up for a minimal secure forum, and by default they don’t allow active code to be posted. You can post it if you put it in a zip, which it sounds like you’ve figured out already.
