Welcome on this platform! Hope you will enjoy your stay.
Now I would like to look at at your "question". (Note: In order to answer your questions quickly use the search function in the upper right corner and enter your questions.) ;)
The number of posts varies between 20 and 50. The exact number depends on the number of spammers. On the other hand, with the Premium or Elite membership you will be able to embed images, without hitting the postcount requirements.
Kind Regards,
