I need a plugin in for Elgg that can handle job posting. It needs to appear in the elgg toolbar, interfacing with the profile is a plus but not necessary. The primary concerns are uses the same login system and admins on Elgg are admins on the job postings. Users can create listing and anyone can view listings, preferably the admins can change this. It should have it's own category system, separate tables from elgg that supports Categories and Sub categories with the ability to search by each/both. If a user wishes to reply to a job they need an elgg account. This can be done by hiding contact fields to logged in users. Also there should be a link to the profile of the user who created the job (only for logged in users).
