The limit is because nearly all upload programs have a limit of 2Mb for file sizes.
Using the forum to send files (esepically large ones) to other users is a very bad idea for a number of reasons:-
- Small file limits
- Not very secure and can allow a hacker to get into the server
- Upload components are very resource hungry and usually mean the
rest of the site stops working while the file is being uploaded, making
the site look like it is not working.
- Anyone can download the file, unless you use windows
authentication which can be difficult to setup and require the user
enter a windows username and password
To be honest you would use less resources and be better off using email
to send files or setup FTP accounts so that users can FTP files to each
other. Or even just use MSN messenger as we do to send files around the
office to each other.
