One up-vote for you good man :D
No worries! Wipster was certainly my favourite in terms of its user friendliness (all you have to do is look at it and you get how it works which is a lot more than I can say for other platforms) so I'll certainly be keeping an eye on how you guys develop going forward :) Good luck!
Many agencies I've freelanced for will build a dedicated web page to act as their client review portal so really you could do it yourself but I know what you mean. Personally I've been through most of them (Wipster, ProofHQ, Frame, and a few more) and I've eventually settled for now with Arc9 as they were the only guys that scaled the package to how many users you have rather than having to pay for extra seats I don't need and I can just scale it up when I hire freelancers in for a few weeks. They offer some nice features like exporting the contextual feedback as an xml so you can literally throw your feedback straight onto your timeline as markers which is awesome, plus Slack integration which is nice. The thing I have a problem with though is the fact that none of them bridge the gap between pre and post production which means I still have to run everything in development on an entirely different platform (for me it's a mix of Basecamp and Slack) as you can't have a conversation without it being "around" a file or piece of media. As in you can't talk about ideas for example without you having a file to have the discussion around. I did however have a pretty exciting email yesterday from Cage who I had taken a pass on before because it was just more of the same but a little pricier that Arc9. Apparently they have built a new version of their platform which will allow you to have conversations without uploading a file first which means if it does what it says it does I can actually stop paying for 2 platforms and finally have something that allows me to plan a project and then take it straight into post without pissing off clients with endless subscriptions that they have to sign up for :D
Wish I had time for this! It's a bit bizarre though that the judging criteria considers "overall entertainment" as the least important contributing factor. Ha!
Ps. That's actually just answered a question for me so thanks ;)
