As you've undoubtedly noticed, things look a bit different around here! The LGW Forums have underwent the biggest upgrade since 2010 and there are a lot of significant changes -- far more than I think I could meaningfully gather into this post. Many you'll notice as you continue to surf the forums as many of the enhancements are functional. Bullets:
There are currently two "main" template skins, labeled "White" (the default one) and "Red" You're free to switch among them as you see fit by clicking on the "Change Theme" link at the bottom of the page.
Removal of profile pictures IP.Board opted to merge the two into one avatar, and as of the last update I believe that remote-linking of images for avatars is no longer permitted (security risk).
Speed The forums should show some significant speed improvements. Some of this is due to inline updating: Posts can be added to threads seamlessly. I'll continue to try to make as many speed improvements to the forums as I can.
More integration with social media You'll see the ability to add topics to your Facebook/Twitter accounts.
Rep System replaced with "Like" button No more +/- functionality as it has been replaced with a "Like this Post" button.
Topic Preview When viewing the forum index (like 'General Discussion' here), you can mouseover a topic and see a dark gray down arrow icon appear to the right -- click it to expand the topic to view the first few posts before going to the topic page itself.
TapaTalk functionality is BACK Some members have been clamoring for it to return as a mobile viewing option, so here it is. TapaTalk is now compatible with the forum (in addition to the standard Mobile theme that's also available if you're still looking for an easy mobile browsing solution.)
Custom Topic Tags Options vary by forums and by member group, but there are now customized topic tags (or 'badges'). In the past it was limited to "PINNED" and "POLL", but I've expanded that to include "GDT" (for Game Day Threads), "SIGNED" for *official* signings, and "TRADE" for topics discussing an official trade. (Do not abuse this ability! It's a great visual aid for visitors of the forums and those that abuse it will be promptly suspended/banned.)
Better Spam Protection All new registrations are IP checked against a known spam list remotely hosted and updated. This should help eliminate a large number of spammers that manually attempt to register and stops them before even seeing the registration form.
New Profile "Statistics" Tab Just what it says: No see just how addicted you are to LGW by looking at your recorded posting habits by time of day and by forum activity.
Gallery Link added to Profile A new "Gallery" tab has been added to your User Profile, for quick access to see what user's have uploaded and shared with the community.
Topic "Tags" These replace the the topic subtitle (the smaller, gray text that was present on the last version). You can enter up to 10 per topic, separated by commas. Use vital keywords describing the topic, like a player name, team, etc., and it'll help catalog forum topics more efficiently to help search engine spiders and the search feature here work more efficiently.
There are plenty more, and I'll add to this thread as I can -- right now I'll be tending to little bug fixes here and there that tend to pop up following a major upgrade like this. (Also, if any members see something I didn't mention, please feel free to add it here!)
