This idea is great and all but the problem is threads like that tend to build up over time as people add deals, then things go out of date and people get frustrated or don't bother to track it. Also multiple people adding a deal might not bother to read through the last several pages to see if it was already added so you get multiple posts for the same thing, this also takes up server space with outdated sales and such.
It would be nice to have a thread where sales can be posted for a moderator to add to a list in the first post and then remove the extra posts they can then edit the list when they are out of date but this requires more time from the moderators to manage it.
What I'd like to see instead maybe is a separate page linked in the top banner next to "About Adisc" with sales that any member can add to or remove from (or perhaps have an auto timed removal if you set a date the sale ends when adding it) that would make it easy to find and track without work from mods and much less server space, you could even set a notification system for it when new sales are added.
Not sure if this system can do that though.
