About:
|
|
This social bookmark services plug-in(feed edition) provides a basic social bookmark servies integration into Serendipity via RSS.
|
|
Supports xFolk microformat standard (RC1, see http://microformats.org/wiki/xfolk); that's why taglinks aren't configurable, I guess ;O)
|
|
|
|
Based upon:
|
|
Most of the source code was copied from the S9Y del.icio.us plugin v0.2.3 by riscky (thanks!)

|
