Now that Nightcrawler's back, maybe he could work on the patch uploading code so you don't have to host them elsewhere.
You can -still- submit patches like always. Our rules apply however, so no unfinished WIPs and hacks which don't meet our submission criteria. For sharing this stuff you'll still have to use your own webspace even after the code got revised. I have a feeling there is some sort of misunderstanding around
To clear things up...
You can submit hacks to the site normally
You can talk about everything hack related on the board
For sharing WIPs and hacks like sprite changes which don't meet our criteria you'll have to link to your own webspace - please don't use the board attachment space for that
When the submission code is revised you'll be able to update your own submissions, aside from that nothing will change from now.
I hope that's clear now? If not don't hesitate to ask before more "we don't accept new files" rumors circle around...
