We'll discuss giving you the option to edit your own posts.As for the SourceSafe issue... SourceSafe is going to be slow over a VPN... it just is. If you put a packet sniffer on the network, you'll see what I mean. Just to check out a single file, it opens an inordinate amount of file handles on the database (which is file based). The web option is slightly faster, but not on the same level as a decent source control solution that uses web services and a SQL based database.
If Team Foundation isn't feasable right now, then there are other, 3rd party source control solutions that might be possible. I've heard of SourceGear: Vault (www.sourcegear.com), and it should be much cheaper than TFS.
