I've been trying to download OSMF 1.5 but the site has been down for a while and i haven't been able to get to it. Does anyone know of any other links where I can find it? All the links I've been finding so far have been out of date. Looking forward to your feedback.
In addition to the svn trunk still being reliably up (as Brian indicated), for the most recent build release zip the download links remain live from this OSMF team blog post!
(The links that the blog post points to download from the domain download.macromedia.com ... which seems to be excluded from the disruption impacting opensource.adobe.com.)
