Hi,

Based on your post, it looks like you're planning to share a technical blog. The TechXchange group is intended for general questions about the community itself. For blogs, the best place to post is the topic group that most closely aligns with your content. Topic groups are where members who are interested in specific products and subjects spend their time, so posting there will help your blog reach the right audience. You can find the full list of topic groups by clicking the Topic Groups link at the top of the page. Please also note, that first time posts will go into moderation for review and can take up to one day to appear.
