I have already stated the reason for limiting edits in the
first thread on this topic and I think they've been repeated since, so I won't go in to them. I didn't make an announcement about it at the time because, frankly,
I didn't think it was that big of a deal. I guess I may have overlooked the specific requirements of the 'Trading Post' forum when making my assessment. However, aside from that specific case I still can't see many reasons why old posts would need to be edited on a regular basis. Sure, you may notice a spelling/grammar mistake, but that's the reason for the edit period. After this, a PM to one of our friendly moderation staff will (in most cases) get the post edited for you. It may be best to use the "report post" functionality to send a request – as this will be seen by all moderation staff. Of course, with this limitiation the old adage "think before you speak post" becomes more relevant than ever. I personally make good use of the forum's "preview" functionality to read over my posts before I submit them and I encourage everyone else to do the same.
The 'Trading Post' forum is a unique case where the ability to edit posts in retrospect is a worthwhile thing to update listings, etc. Unfortunately, phpBB has an all or nothing approach when it comes to this, so there is no way to enable editing past the limit in only one forum. phpBB also doesn't have any sort of edit versioning/history system which someone mentioned – if it did that would obviously be a preferable solution. While I understand that this is a bit of an inconvenience, all I can ask is that you appreciate why we've brought in this limitation and make the best of it.
As for the membership purges, since someone brought them up, they are necessary to curb the number of spambot "sleeper" accounts* that we have had since the upgrade to phpBB3. Since the reCAPTCHA plug-in we were using before doesn't work with phpBB3, we have had to put up with an increased level of these type of accounts registering. It's a pretty arduous task to go through the new registrations and weed out these one by one (we were getting in the region of 30 a day for a while), so realistically a purge is the only way to do it. Sure, it may catch the odd member who has signed up but hadn't got round to posting, but I'd think that the ratio is pretty low. It does not affect any member who has made at least one post, so shouldn't make a difference to anyone else. I've recently been experimenting with adding some anti-spambot questions to the registration page (as I mentioned
here) which seems to have worked nicely – so hopefully in the future I won't have to do these purges quite so often.
Cheers all,
