I'll admit I was one of the silent viewers of your topic. I'm not playing the pack in question, but I enjoy seeing pictures of people's creations. I also have a bit of OCD which makes me read (or at least scan) each new post in the General and Community Showcase areas. I know you had mentioned in a thread that you started a thread with pics of your world then removed it due to lack of interest. It so happened that I was interested in this, but my In-laws were in town. You had removed the thread before my free time opened up again. Be patient. Some of us are regulars, but most stop in once a week or less.
Honestly, I doubt anyone was intentionally trying to snub you. There are times when these forums go completely silent for days, then others when there is a flurry of activity. I've noticed that the Community Showcase in particular suffers this wave. Sometimes even the best thread gets buried/forgotten. Sometimes the people who are interested in a thread have Real Life to deal with. Other times nobody is interested at all (not saying this is the case with yours, but a ton of single digit post threads come and go).
I can't tell you how many times I've started a thread that I thought had the chance to be the next "What cool thing have you learned today?", only to have 20 views and only one response. Shit happens. Brush it off and move on. Or don't. Totally your call. But if you let one no-response thread cloud your entire experience here, you're missing out on the other great things these forums contain.
