Cons
Con Poor search, unless using Sphinx
The default search that comes with Vanilla produces poor results because it uses MySQL. One needs to investigate integrating with Sphinx for much better results.
Con Vanilla Cloud offering is expensive for bigger communities
The commercial options of other software providers are generally better value-for-money. Vanilla is a cheaper option if you commit to self-hosting.
Con No post edit history
Old versions of a post are only visible to admins, which may lead to a credibility problem. The amount of time during which users can edit their posts is configurable from a few minutes to indefinitely.
Con Templating could be better
It is difficult to customise Vanilla in a way where it can be source controlled. This may be a benefit for communities who just want to get up and running, but is a drawback for developers.
Con No sitemap for discussion
Even sitemap plugin cannot add discussion in xml file.
Con Limited themes and extensions
And community is fairly small as it is derived from SMF Forums.
