I don't see anything wrong with the urls for the board, they look normal to me.
However, I do see the phpbb-seo link at the bottom of the page. normally with that MOD the urls would be "human readable" and they are not. THey are normal.
bottom line is that you do not need any of that for google to index and rank your phpbb board pages just fine.
I would suggest that you not worry about that. If your listings in google are with old urls using the SEO stuff then you can do a 301 redirect in the htaccess file that will make it all work for you.
your board is a phpbb2 board and the current version is phpbb3. if you want to keep the older version you will have to get help somewhere else for it because it is no longer supported here.
is the only phpbb2 support site I know of.
if you want to upgrade to phpbb3 there are fairly simple instructions to do so.,
you will not lose any of your members, posts etc.
however, no MODs that were installed on the old board would work on the new one. I don't see any MODs on the board but that doesn't mean there are none.
someone added the main site header /menu to the subsilver style template files so that would have to be done again but that is not very hard to do.
If you need help upgrading ;
Information on how to convert from phpBB2 to phpBB3 is here
Basically, you must have both phpBB2 and phpBB3 installed on the same server. After you have finished installing phpBB3 you will have the option to convert your phpBB2 board using the built in converter. The information it asks you for is related to the phpBB2 installation and can be found in its config.php file on the server. All of your users, posts, forums, PMs etc are converted. However, styles and MODs are not (with the exception of the birthday and attachment MODs which are supported by the converter). The phpBB2 database is not converted per se
, it is merely read and converted/moved to the new phpBB3 database, so if it goes wrong your old board will not be affected at all. At the end of the conversion, once you're happy it's all working, your phpBB2 database and files can be backed up and removed if you so wish. They are not connected to the new installation in any way.
