Sorry for the following problems:
1. It is hard to sign up for blog notices - I sent a support request a few days ago but have not heard back yet. I think it is browser related as there are differences between the mobile and full version.
2. Unable to post comments - I reviewed this issue today and I also think it is browser related.
If you have other problems please send me an email @ email@example.com
You can also send comments to me direct if you wish
