15 year old requires acting job

I think that's a very unfair comment. Many professional techs, actors, directors, designers (and whoever else is out there) check websites. They check them for information, sometimes for jobs, and sometimes just to talk to people in the same area. True, there seem to be more people posting who aren't professional, but that's simply because they don't have as much day-to-day contact with professionals.

I myself don't like the constant posting, but am also sick of the lack of communication between the emerging artists and the professionals.

You hire people based on their skills, their enthusiasm and their dedication, not by how much time they spend on the internet.
And if you are not hiring people based on their skills, but based on their amount of internet time, then that should be counted as discrimination (unless, of course, if they don't come to rehearsals/performance because they are on the net...in which case, you probably shouldn't hire them... but that's lack of dedication isn't it?)

I have been in the professional world of theatre for three years now, and find it incredibly necessary to check websites, especially Artshub, and this site also contains a lot of important ads and info that I sometimes need. I run my own theatre company, and sometimes I need to find a particular item. Last year I needed a hat with a propellor on it, posted a query on this site, and Craig Williams was nice enough to lend one to me - despite our being in different states.

And by the way, doing a show like that may give a person a 'full theatrical experience' but it doesn't guarantee a long-term career in the industry. Perserverence, hard work, and a lot of job hunting does. I have applied for many succesful theatre jobs through this site and others. So have my friends. Information about grants and funding can also be found on the net.

A while ago, I would have complained about all these posts (and they still do annoy me), but now I defend them because at least this provides conversation and advice. If you were finding it difficult, wouldn't you want to ask someone, especially when it seems there is no one to ask?
