Can I grant users permissions to create their own accounts?
Yes, as of SourceForge 4.1 SP3, it is possible to configure SourceForge such that new users can create their own accounts, but the accounts are not activated until a Site Admin approves them.
Why does SearchReindex.sh fail on SourceForge 4.4?
This occurs as the search indexer included with SFEE 4.4, requires the 4.3 java SDK. You can obtain the java 4.3 SDK at the link below. Extract the file to /usr/local/sourceforge/sourceforge_home/sfsoap (assuming you installed SourceForge into /usr/local/sourceforge).
