-Not really a lot. We had like 2 proven (and fixed) in last week but overall we have only 8 in the whole 2014. 8 bugs in a whole year is an amazingly low number. I would call it a lot if we had like 20 a week and I would only be concerned if we had many fixes pending. This is the most important part after all, to FIX any bugs found and we are doing a great job here in fixing bugs in really short time.
To close it up, every serious application has bugs. The bigger it gets, the more bugs are probable to be found. There is no software that is bug free after all. Especially games are very prone as they are often pushed to the limit. Online games are even more prone. So keep calm and trust the devs who have taken you this long in such a complex game.
Now, on to your questions:
1)I use TAGS to organize topics in all forums. TAGS help me, you, other players and the devs to keep track easily of what is going on. In DEV forums, this is also required by the DEV team.
Every forum has a team that moderates, same here. I am the admin and there are also player who are moderators. Here is the mod team:
memberlist.php?mode=group&g=4The mod team, makes sure that the forum rules are kept:
viewtopic.php?f=2&t=3The mod team, also helps in organizing the forums. This includes topic title renaming (I do this a lot, I just did this here as well). Topics must be descriptive and to the point and not provocative if possible.
2)You should not be worried at all. Bugs will definitely be the case, but I am confident there will be few of them and we will fix them on time.
