Crosswinds.net.  is the worst  8711
4271 [nlzvnv@ya oo] Hey everyone.  Public service announcement here.  LOL.  I wanted to spare you some heartache.  If you have a website at all DO NOT use Crosswinds.net.  I had a website there for a month and spent hours everyday working on it and have been getting a thousand hits a day and crosswinds.net just up and DELETED IT without even so much as a warning.  now all my hard work is gone.  I contacted them because I thought maybe they made a mistake and they informed me Oh well.  All because i had a song on my site.  I want everyone to know before anyone ever has to go thru this.  Thanks for listening.

  4431 [aleksi.nieme] Dave and Guy proposed the same thing with different words almost
  4432 [decoux@mo lo] perhaps I'm wrong but you need to enable the GC before a call to rb_gc()
