There's a few things that have happened that people have mentioned already like the homographs and the 24 hour bump deletion thing, but don't forget about the merit system as well.
I'm not sure if the merit system was a user proposed feature, I haven't found any info leading to that.
Numerous people including myself had suggested something such as 'likes' or something similar, though merit is a little different and probably works better than others envisioned.
Theymos is probably reluctant to spend too much time coding things for this forum when he's busy working on the new one
....
If I remember correctly, I read somewhere here that this was started sometime in 2015. It's 2018 now, I think it's highly unlikely that this will be done anytime soon, if ever.
Judging by the current pace & developers involved, it will probably take a lot more time that originally estimated.
It's much longer than that. Theymos sticked the thread in the New forum software in March 2014 and it had been in development before that:
https://bitcointalk.org/index.php?topic=523070.0From what I understand theymos is the sole person working on it, so that's both likely why it's taking so long and he has less and less time to dedicate to here as well.
I'm hoping that something will be done about removing signatures from Newbies/Juniors or requiring the latter to achieve some merit to become one. Clamping down on ICO campaigns who do little to nothing other than pay for spam would also go a long way and these are things that wouldn't require much effort from theymos and the staff can take care of the rest.
I think this part with the restrictions to signature display is definitely not working.
I remember when I was a Jr. Member and the ability to add hyperlinks in signatures was removed but you could still display a text (like it's still the case now). As you can see there are a lot of campaign managers who hire Jr. Members to advertise their ICO/project/etc. So, clearly this isn't working.
This is it. They barely have a signature that is useful for anything anyway and it's largely worthless to even ICOs, but they don't care. They pay people for free and at least it gets their name out there they might as well utilise it as they have nothing to lose. This is why it needs to go and wouldn't be a huge issue even if it did. Users can still purchase a Copper Membership anyway to get a signature and I think that's something the forum should experiment with or even move towards (purchasing larger signatures via donator ranks like Silver and Gold etc).
