hey kumarsankar098, it's very cool that you want to support the models and studios, and i hope you are able to get through the membership process eventually.
the sign up info about what you are paying for and how the site works can be very confusing (especially if english is not a persons first language), and i think it needs (urgent) rewriting and clarifying, because yours is the second such 'what do i get for my menbership?' comment from a prospective member this month. and for every forum member that is a forum member and asks here, there will be many more that are not forum members so are not able to ask, and just give up on the process
i'm not able to summarise it all here and now because i'm travelling and and intermittent www connection and time are limited, but this is the thread from earlier this month which asked a similar question:
How to know which videos are in studio membership?
viewtopic.php?f=96&t=91569and hopefully other members will chip in with bits and pieces to supplement that and answer any questions you may have. plus contacting the studio directly to ask is worth a try. they do actually answer questions (support here is not an auto ai bot, it's a real person who knows what they are talking about, which is valuable and rare on subscritopn sites these days)
anyway, have a browse of the thread, and keep asking here. weekends can be a bit slow re feedback to comments, but eventually people will engage as and when they can
