There are plenty of options out there which are cheaper and just as effective as SLG
I have been reading your threads and itís interesting to point out that with some products you can buy into just parental reporting or just teacher access from home? whereas ask yourself if your school is just interested in providing teacher access then why would you want to have to purchase other features bundled in if you not going to use them?
There are many alternatives out there from many suppliers, some of which are already pointed out on here, of course many of which are cheaper than SLG! Worth pointing out as one person has already spoken about it is that Bromcom MCAS and Teachers Webfolder is not reliant on SharePoint as it is a true application, so technically easier to install and use.
