It sounds very realistic that you haven't found any factors in a range that small.
If you got any results they would be in the fact.txt file, so take a look there (if you haven't found any factors yet, the file probably doesn't exist).

As you found no factors nothing should be submitted through the 'Sieve Result Submission' page (http://www.seventeenorbust.com/sieve/), so all you have to do is post

152700-152701 maniacken [complete]

to the coordination thread.

As there is a seperate P-1 factoring subproject, you shouldn't call the main project's test for 'sob Factoring test', the normal term is prp test.

EDIT:
Now I can see in the coordination thread that you reserved the 152700-152800 range. That means that you shall not post to the coordination thread until that range is done (except if it takes a lot longer than expected).
