Are there developer in question2answer?
Yes, I'm the lead developer currently, and there are several contributors.
There are still regular updates happening, though they are smaller as I've been very busy the last few months.
There was a release mid-November, and there should be another minor one before too long (just need to fix a couple more issues).
No new plugins.
There are still plugins being made as far as I know. Maybe there haven't been as many recently, not much I personally can do about that.
Examples? If you submit a bug report here or on GitHub it will get fixed asap. I've fixed loads of bugs in recent months.
No reply to what? I reply to several posts on here, and to issues on GitHub.
The project relies on members of the community getting involved where they can. We have some people who help out here but of course we can always use more!
If you have some more constructive feedback I'm happy to hear it, and I'll do what I can. Thanks.
