I agree fully with what was written by ilbellodelweb, I do not think this is the best solution for a better market but I think they are much more useful the solutions for market improvement proposals from modzzz that a system of subscriptions that only kills the market.
A very relevant market is wordpress where there is not a "subscription system", just the "one-time payments".
This does not deter customers to use wordpress in fact is definitely the world's most popular CMS see more and this confirms that one-time payments not penalizes market in any mode.
To improve things it just takes more control on products placed in market and on the vendors.
in more exist two relevant problems:
1) if market not have many user that buy a subscriptions to $3 a month is impossible to finance the development and upgrading of the modules and this creating the risk that the user not have product upgrade because developer not have finances and abandon the boonex market, only one-time payments allows to finance the upgrading work with a lower number of sales.
2) in case of templates and many other modules with "open code" after is downloaded with only $3 dollars is impossible to impose deletion from a site if user suspend payments, for example if user suspend dolphin subscription and use dolphin with "free licence" what can do boonex to make sure that user cancel all modules already downloaded with only $3 dollars? for not mention those who use a nulled version in this case after have paid only $3 dollar and have downloaded many modules boonex not have any mode to stop the incorrect use of a modules.

Thank you for your input!

First, you won't need to adapt or change your strategy. You can continue as you do. You can, however, TRY to offer a couple of extensions as subscription service. Just try and see if you gather some subscribers and what sort of return it would bring for you.

And see... if we had subscriptions, say 5 years ago and you started gaining just 1 new customer a day, you'd have about 1500 clients now, paying a guaranteed 4-5K every month.

Anyway, it is important to understand see more that we don't plan this as a default policy or the only way to sell - it will only be an additional option. I can also think about something like, say, a package of all your mods bundled and offered for a higher monthly price, supported and updated. Or a number of different bundles.

As for Dolphin pricing and popularity... If you explore this, you'd see that pretty much every social CMS has sinked somewhat. We have spent a few years for Trident development and that also pushed us back. With $99/license price-point we couldn't sustain operation - support was overloaded, but revenue wasn't covering expenses at all. On the other hand, I understand that easier entry would make a big difference, and introduction of Trials and leased licenses already show improvements in general interest and activity. We are growing again.

And I've noted before that eventually we plan to make DolphinPro core package free, with separated modules for a fee (honouring all current licenses by keeping all Boonex modules free for them). We're already doing this with Trident and hope to implement the change in Dolphin within this year. This will make Market very active.
