We had some issues with the "google groups" box that was prominently displayed on the blog earlier. Therefore we switched to Feedblitz, which was the second best option. We've now resolved the google groups issue and have the box back. For those of you who wish to subscribe to SpicyIP posts (this way, you can receive all posts in your email inbox without having to come back to the blog each time to check for new posts), please enter your email address in the said box and you will be subscribed.
Also, for those of you who subscribed via the earlier Feedblitz box and wish to switch over to subscription via google groups (a better format and it gives you the title of the post etc in the update that comes into your email inbox), please enter your email afresh in the google groups box. If you have any issues with any of this, please let us know.
