I wish to submit the deletion of some alias that are blocking some more relevant ones.
A while ago, someone mentionned a particular syntax for that, but i can't seem to find it.

As far as I know you can't, so either use the forum or IRC to discuss a bad alias.

It's not a matter of alias being bad, but rather being replaceable by something better.
For example, i'd replace :
14_bis -> 14-bis

by :
14_bis -> fernando_faria
14-bis -> fernando_faria

Well, here the list of those i'm thinking of :

Delete :
boobsquish -> boob_squish

Replace by:
breast_squish
______________________________

Delete :
thighhighs -> thigh_highs

Replace by:
stockings
______________________________

Delete :
micahfennec -> micah_fennec

Replace by :
moody_ferret
______________________________

Delete :
miupix -> miu

Replace by :
michael_vega
______________________________

Delete :
boob_grab -> breast_grab
boob_squeeze -> breast_squeeze
breast_grope -> breast_grab

Replace by :
breast_fondling (or something better, there is probably much to discuss on this one)
______________________________

Delete :
wookie -> wookiee

Replace by :
Nothing ! Let us tag Star Wars wookies.

... Um... You know, the Star Wars race actually DOES have two 'E's in the name, and it's a common nerdrage topic. The artist's name IS supposed to be that, and they actually DO have it spelled correctly.

Personally I'd recommend leaving the alias, but going ahead and using a new 'wookiee_(star_wars)' tag as appropriate.

Other suggestions:

<hr>horse_cock -> horse_penis
< REDIRECT BOTH TO >
horsecock
<hr>
Will add more once I remember what they were.

Kald if I catch you on the IRC we can go through any you've found and I can manually make adjustments when I have some time. If IRC is bad, just let me know in this thread, or whatever.

Note that I also have the ability to mass-replace all tags of one name with another, which can be handy at times.

I never used IRC, but even if i did, i'm mostly online during the evening CET (noon in america).
