I use Joomsef 3.2.1 and Fireboard plugin,

Exclude ID from URL YES
Exclude do action from URL YES
Reduce URL count YES

but

if
do variable = delete/merge/split/etc...

it creates

post-1.html
post-2.html
.
.
.
post-XXX.html

@ delete,merge,split,quote; ID paramater always must be non sef variable i think.

But now, it creates a lot of link. :(

It is a bug or...?

Thanks...

What FireBoard version do you have installed?

You can see the extension in action at this very forum, however, there are no merge & split tools, so I believe you may be using a different version.
More likely than a bug it appears the version you are using may not have the full support. Please, send us the version number and we will check it.

Anyway, all "do" variable get excluded. So also make sure the "Append non-SEF variables to URL" is set to yes.
Also make sure you are using the latest version of the official JoomSEF plugin for FireBoard (available free from our site).

I use

Joomla 1.5.8
Artio 3.2.1
Fireboard Joomsef plugin 2.0.0
FireBoard 1.0.5 RC2

and Append non-SEF variables to URL is YES
