Process Engineering Division: Technical Discussant Assessment and Bonus Distribution Notice for August 2009 (Maximum reward increased starting from this issue)
Thread Content
Please have the technical discussants in this section read it carefully and reply with a follow-up post to claim the bonus. I. Purpose of creating this post: 1. To help members learn* the technology more effectively and improve their technical skills. 2. It is hoped that technical experts will serve as role models, setting an example for members in terms of technical exchanges and fostering a climate of technical interaction within the community. 3. It facilitates an overall assessment of technical experts’ monthly contributions (the number and quality of posts), so as to provide a basis for awarding bonuses. 4. It facilitates members’ supervision of technical experts. II. How to use this post: 1. Technical experts can post replies under this post, sharing their own topics or responses, as long as they believe they hold some value. (Uploading materials and sharing content are not included). One floor per expert, with all links published centrally. Posting format: Serial number: Post title, Post link (see the tutorial at the bottom for how to copy it), Floor. Example: 1. XXXXXX post, XXXXXX (link), Floor X. 2. XXXXXX post, XXXXXX (link), Floor X...... 2. Technical experts are requested to post here by September 10. The assessment period for this post is from August 1 to 31. Due to the forum’s current restrictions on when posts can be edited, this post will be published on the 30th of each month; technical discussants are requested to reply with their comments as soon as possible. 3. Please provide the link for August in the reply. 4. Moderators who also serve as technical experts may reduce the number of relevant links appropriately, but the number of links must not be less than 30. 5. The monthly bonus assessment is carried out by Chao Ban (that is, the individual himself). Based on the number and quality of links posted in the comments by technical experts, along with other factors, a comprehensive score is determined, and bonuses are awarded according to this score. Those who fail to meet the rating standards for three consecutive months have their title of technical expert revoked. 6. The maximum bonus this month has increased to 500 Wealth points! III. These measures shall be put into trial implementation as of the date of issuance. If you have any questions, please contact me promptly. IV. Non-technical experts are requested not to reply to this post! Non-technical expert responders – 3 charm! V. We welcome everyone to actively participate in the development of the forum and join the team of technical experts!
