I've checked some translated webpages, and here are the (technical) errors I've found:
(june 13th) Fixed the list concearning the entity-use
(june 13th) Added "Deutsch", "Português" to the list
(june 13th) First update
I checked for:- Missing translations
- Too long lines
- Proper use of entities (<= many mistakes there)
I didn't check for spelling, nor gramar, nor any other language-rules.
Afrikaans
seems ok

$LANG_registryt is too long to be good. The text should be on 1 line to make the hooverbar nice-looking.
$LANG_storet is too long to be good. The text should be on 1 line to make the hooverbar nice-looking.
$LANG_supportmsgplus is too long to be good. The text should be on 1 line to make it nice-looking. (maybe change
msgplus! to
Plus!)
$LANG_features7 has a bad entity-character: ".....atractiu l'
&uacte;s...."

$LANG_dllink2 is too long to be good.
$LANG_dlmessage is too long.
$LANG_registryt is too long.
$LANG_size is missing.
$LANG_dlbutton1 is missing.
$LANG_dlbutton2 is missing.
$LANG_forumt2 needs to be translated too, although it must say "English".
$LANG_aboutt is maybe too long, needs to be checked after
$LANG_registryt has been fixed.
You need to change all the special characters to their representative entities.
This means changing characters like å,ø,æ, etc. to things like é, à, ·, ø, etc. (see endnote for more info).

There seems to be a misplaced ";" in the beginning of the page (after the body-tag). This can't be fixed by the translators, but needs to be fixed by somebody who has access to the page itself (Guido, Patchou?)

Note about the entities:
Each character with an ascii code bigger then 160 or unicode-character must be written as an entity! Characters with an ascii code between 160 and 255 can use the entity-name format and unicode characters should use an entity numeric-format.
Lists of these entities can be found here:

[ALL TRANSLATORS] faults in current translations for website

we'll change it.
