Only way I have found to increase it is to create threads, but you have to wait for them to be moderated and not all of them will be approved. So I just pop every few days, post, like and try and create a few threads and see if it helps. I also wouldn’t try to create too many threads at once, but in time you’ll get there. I’m about 19 threads away from the 100 I need. At least I’m out of the negative.
