Exactly, don't like it, don't use it.

I don't understand how people can be so ungrateful, they have no idea what went into this or how long it has been in the works.

Everyone has different needs and priorities so please don't try and enforce your needs on to others that have different ones.

Now, back to the original question...

Does anyone know if there are any adverse SEO impacts with using this mod...thanks

In my case, all I want a way to have 3 forums in the same domain, like for sample, English forum, Spanish Forum and Portuguese Forum all in subdomains from the main one. like;
www.domain.espanol.com
www.domain.com
www.domain.portuguese.com

That will be the use I want from this Mod

Still waiting a good How To so I can make it work

Just FYI, subdomains always go BEFORE the domain...
as in:

espanol.domain.com
portugese.domain.com
etc...

Installed on one of my 3.8 sites and was going to look at it/configure it latter but it seems to have broken my ability to login to the ACP :erm:

And from my reading it seems not to work on 3.x anyways :(

Oh well... Anyone have this for 3.8???

It is in the 4.0 Mods area. :)

The similar 3.8 mod is here: https://vborg.vbsupport.ru/showthread.php?t=251149

While I got the fatal error on the login page, the login itself actually worked so when I reloaded the original page I was already logged in and able to disable the mod.

It wouldn't hurt for the developer to put "4.0.0" as the minimum VB version needed so it won't accidentally be installed on a 3.8 board.

I know it is 4.0 but this lead me to beleive it should work. Again should be coded for minumum version requirements as a safety net.

If you had kept reading I did mention the error encountered on 3.8:

I'm unable to make it working with plesk, vb 4 and vbseo

In plesk I tried a subdomain and a Frame forwarding for an other domain.

:(
