Even the regular girls on there move around a lot, I cannot see it being current no matter what effort is put in.
Thats why some are listed as touring. Maybe it needs a seperate category...
Also remember SE is a vast area with dozens of local punting hotspots and notspots so you'd need a fair number of volunteers well spread around.
Depends if people only want to update their own region or not? Doesnt take much to notice when a new positive review pops up to have a
quick look to see if the wg is already on the list and if she is that her details are correct? Are people now not already doing something similar indexing reviews, updating titles etc? Obviously updating the wiki page is slightly more complex so like I said it just depends on if people find it useful, have the knowledge and want to do it or not.
