We are reaching out to all our members, as our records indicate that in several cases membership fees have not been settled over the past two years. As you know, the EFS is a volunteer-based federation that relies on the active support and collaboration of its members to continue its scientific, educational, and outreach activities. If your membership fees have been regularly paid during this period, please consider this message not applicable to you.

If for any reason you have been unable to pay the fee in the last 2 years, as an esteemed part of our community, we sincerely value your contributions and would be delighted to welcome you back into active membership. To support this, we are pleased to offer you a 20% discount on the membership fees for both 2024 and 2025.

We kindly ask you to regularize your position by taking advantage of this special opportunity. Please note that members who do not renew their membership by the end of the current calendar year will unfortunately be considered outside the Federation and will no longer be entitled to the benefits of belonging to EFS.

This is an excellent occasion to rejoin the Federation — especially as we look ahead to the 2026 EFS Congress in Lisbon, which promises to be a milestone event for our community.

We warmly encourage you to seize this opportunity and remain an integral part of the EFS network.

Should you need any assistance in completing your renewal, please do not hesitate to contact us.
