• Even though I read a lot of topics, I am unable to answer to them, since either they have already been answered or that I don't have enough knowledge about the subject being discussed.
Trust me, we all have topics we don't have any idea what is being discussed about or what/how to answer. At that point, all you have to do is just keep on reading and researching the said subject if it interests you. For example, I cannot answer to like >85% of the technical stuff and almost anything related to mining. There's more stuff I can not answer to than just that, so we aren't much different. Some members have a very, very broad knowledge when it comes to mining. We all have different interests.
• I don't have a special skill set to offer some services in the services board nor am I able to make enough time to manage something like that, but I am looking into myself what I can offer so that people can benifit.
It'd be nice if you could find some way to offer something for BTC on here - the more people offering stuff we have, the more Bitcoin grows. But that is not a requirement. I have personally tried launching a little signature campaign management service, but I did not have much success. Try to find a niche that hasn't been discovered yet. You might do great.
• I felt like I am being left out, it's been a few months since I am on the forum and my progress has slowed down drastically, I feel like I lack a little bit of something.
What exactly is it? Try to find out. You're probably trying way too hard to post threads wherever possible to just get those merits. A lot of my merits came from posts I never thought would get rewarded. Take your time to look through threads and reply whenever you feel like you have a point to make. Otherwise, it gets exhausting and annoying to reply to stuff you aren't interested in.
My post count per day has drastically slowed down as well lately for many reasons - not having as much time as I had a few months ago is one of them. The thing is, it's much better to post once per day but have a higher-than-average quality than posting 5 more times and spamming everywhere.
So long story short, just reply to stuff you're interested in and try to prioritize quality over quantity (what an ironic statement coming from me, the probably longest and most boring reply writer around here). Things will get better in time.
