Please be more specific.
You want to download Plugins?
https://plugins.b2evolution.net/
Is it SHORT LINKS? That is automatically installed in your B2Distro.
Here's a cool post about it
https://plugins.b2evolution.net/short-links-plugin
Want to find it on your server?
Public_html_plugins/shortlinks_plugins

Cant Find your Plugins?
<your site>
Go to backend
system
plugins
Clear dot (Disabled)
Green Dot (Enabled)

In the upright corner you can also see
+Install New

If the above doesnt help, please go into much detail as you can and post pictures.

And may I make a suggestion? Making snippy comments will get you ignored by staff. Been there, done that. Be patient.

Downloading plugins was my goal, but other than the one plugin those that are tagged with "download files available" don't have down load links. That is annoying.

@mythusmage

1. Please detail which plugins you want and can't find.
2. Please detail what you did that resulted in the problem of noit getting what you want with screen shot of the page where you tried to access the plugins you want.

Your complaint is clearly noted but @mikes said 'Please be specific' you can't really expect someone to go through all the links to find out which ones work etc. :)

If some of the plugins don't have download links maybe they are obsolete and maybe included in the core diownload yet are still listed as an archive of historical options.
