Tried a bunch of things on my own first but kept hitting dead ends.
The free tiers on most of what I've tried are basically useless — you get just enough to see that real people are there, then hit a wall the second you try to actually message anyone.
I've tried a few different things already with mixed results. Some were complete time wasters, others were okay but nothing that really clicked.
Any input is appreciated, whether positive or a warning. Both are useful at this point.
