* BBS View renderer module for WebCit
*
* Note: we briefly had a dynamic UI for this. I thought it was cool, but
* it was not received well by the user community. If you want to play
- * with it, go get r8256 of bbsview_renderer.c and have fun.
+ * with it, go get commit dcf99fe61379b78436c387ea3f89ebfd4ffaf635 of
+ * bbsview_renderer.c and have fun.
