I'm trying to decide the best way of updating my website. I have a forum, which is 7 years old and is made on WBB 3.1.2. It's a big community with 5000 users. I wanted to give my community something fresh-looking and I wanted to add more features, like Marketplace, custom pages, Wiki-engine integration, mobile version support, and what's most important is a project database, since my forum is about game design. I wanted to create a multilingual community, where every user can create and manage his team and projects in the projects gallery. And I really wanted to work with something that isn't only locally supported, but rather a forum/cms engine that has a wide international community in terms of support and plugins. I remember how difficult it was to code for WBB 3.1 back in 2010 and how uneasy it was to find the required plugin or to do something unusual beyond of included features of forum software. The weak points of WBB was a lack of Russian language by default (I had to do translate the whole thing myself), small amount of plugins available (there was only 2 or 3 news plugins and 2 file base plugins available) and a small local community. As a result it was extremely hard to achieve the things that could be done in a few clicks on Joomla or Wordpress. I couldn't even create custom pages on the old version.
But of course it would be much easier for me to upgrade old forum for a new version than to move to some other and entirely different platform. But I'm not sure if this (WBB) platform will be scalable in future and whether it will suit the fast-growing community of game developers.
Advantages of upgrading to newest WBB:
+ease of migration
+similar forum software that is well-known to me and my community
+obvious advantages of v5 against v3 - I really love what you've achieved over past few years
+official filebase app (for a fee)
+Built-in free Articles/news feature
Disadvantages of upgrade:
-Lack of Russian localization by default, didn't find any Russian localization on plugin-store
-Small community, less plugins available as a result
-Less possibilities comparing to CMSes like Wordpress and Joomla
-Proprietary API and difficulty to code some custom features
-No way to integrate with other CMS engines
-High price comparing to free Wordpress/Joomla
Am I right on these points?
What can you suggest me to do in my case?
Is there any possibility for official Russian localization?
Is it worth of upgrading, or it's wiser to transfer the data to a new system that can grow bigger?
Thank you in advance!
