Do the links from top websites' forums boost in-terms of backlinks?

If we get any backlinks from discussions/forums of top websites like wordpress and joomla forums; do they count as valid and authority improving backlinks? I mean about the dofollow links.

This depends as some forums have all of their outbound links set to "nofollow", which mean they pass little to no SEO value. Quite a few are "dofollow" which means relevant forum participation that leads to a backlink to your website will help in terms of SEO value. Forum participation in general is a good practice if you can find quality forums for your industry and niche, I would just not overdue it with pointing links back to your site, unless it is 100% relevant and beneficial to the forum. For example if there is a discussion that is going on about a topic you happened to write a blog post on last year, you can reference the blog post and provide a link back to it in a comment in most cases.

Be sure to read the guidelines for each and every forum you want to participate in, as they can sometimes have strict rules, also a good practice is to do 10 or some comments w/o links before trying to provide any kind of backlink to your website.
