I have been using wmpudev plugins since 2010. Now I'm considering renewing my membership.
As a website developer with main insterest in wordpress, I also value time and professional supprot. What I need in my projects is well writen, fully supported,wordpress plugins. In my project I use Autoblog, Infinite SEO, Recent Custom Posts/Comments among many others, especially plugins dedicated for multisite functionality. I also implement wpmudev solution on standalone wordpress sites.
During each project, I spent many hours with wpmudev consultans discussing issues and asking - questions or issue has never been left unanswered. In addition, some projects showed that external wordpress solutions work fine with wmpudev plugins - like localization standard WPML or independent theme authors (e.g. on themeforest), who provided dedicated fixes and support. It is fantastic experience to know that you can count on the platform you have chosen and have reliable partner to work with.
5 stars service, thank you and despite of the fact I'm working less with wordpress nowadays, I am staying with wpmudev.
